Source apportionment and pollution loading in Lake Chini watershed using multivariate statistical analysis

This study was conducted to assess the surface water quality and sediment contamination status in the Lake Chini and its major tributaries as well as to find out the sources of pollution through different statistical techniques. 15 potentially important locations were selected for water sampling and 10 for sediment, after completion of a survey, whereas 5 geographically important tributaries were selected to understand the pollution loadings they contribute downstream. Water samples were collected six times following standard methods, covering both dry and wet seasons. A total of 16 physicochemical and biological parameters along with 5 heavy metals were measured. Obtained data was compared with NWQS (National Water Quality Standard for Malaysia) and WQI (Water Quality Index) Malaysia as well as multivariate analysis. For sediments, sediment quality guidelines, geo-accumulation index (Igeo), contamination factor (CF) and pollution load index (PLI) were used to evaluate the current data and its status of contamination. From the study, it was found that DO, BOD, COD, total coliform and Fe were higher than the permissible limit in water. Source apportionment study revealed that the major sources of contamination were due to anthropogenic activities especially settlement, mining, agriculture and illegal logging. There was a prominent increasing seasonal trend from dry to wet season for all water quality parameters. Overall water quality at all 15 stations was categorized as class II (suitable for body contact), but having two different contamination status; clean and slightly polluted. Stations at tributaries, draining area of the lake and at the mining area were slightly polluted. Sediments were detected acidic with high organic matter while Fe, Co, Pb and As were higher than the LAL (Low Alert Level). Only Fe value was found beyond normal limit according to contamination factor (CF) while Igeo and all others were within the normal level. Heavy metals pollution status was higher near the tributaries catchment (especially around the mining area) although it was acceptable. Heavy metals contamination had an increasing trend from dry to wet season. However, both water and sediment were contaminated higher in the tributaries channels compared to the lake. The water quality of the lake is class II (88.37) that could be used after conventional treatment and is safe for recreational purpose

A Fuzzy ANP Based Grey Relational Approach to Evaluate CRM System in Context of Bangladesh

This study aims to select a suitable CRM (customer relationship management) system among different possible alternatives for organization’s in Bangladesh. Since, evaluating CRM system on the basis of lot of attributes leads us to Multiple-criteria decision analysis (MCDA) problems. In this study, a hybrid MCDA models were used. FuzzyANP (Analytic Network Process) and GRA (Grey Relational Analysis) approaches were adopted to solve the problem. The study explored that the Hubspot CRM was optimal solution in context of Bangladesh. Our research will beneficial to the organizing for better customer support.

Attitudes and risk factors of pornography consumption among Bangladeshi university students: an exploratory study

Pornography is extensively produced, distributed, and used as a medium of entertainment around the world but has been little studied in Bangladesh. The present study examined the attitudes and risk factors of Bangladeshi university students’ pornography consumption. A survey was carried among 313 undergraduate students at Jahangirnagar University (Dhaka, Bangladesh). The study found that 72% of students consumed pornography at least once within their entire life, and approximately half of them were occasional consumers. Approximately two-thirds (67%) encountered pornography during high school, although females typically encountered pornography much later. Logistic regression analysis showed that pornography consumption was predicted by being male, living in a rural area, being in a relationship, engaging in online activities (such as using Facebook), and watching movies. Further research is needed to further determine the behavioral patterns and associated factors that influence pornography consumption among Bangladeshi students

Health Problems and Health Care Seeking Behaviour of Rohingya Refugees

Background: Rohingya refugees are one of the most vulnerable group due to lack of health care system, personal hygiene, shelter, sanitation and violence. Aim: The present study aims to find out the health problems and health care seeking behavior of rohingya refugees, to identify the socio-demographic information for such exposure group in relation to age, sex, occupation, living areas, to explore the patient’s physical, emotional, perceptions, attitudes and environmental health problems and to bring out health care seeking behavior of refugees. Methodology: A cross-sectional study was conducted. A total of 149 samples were selected conveniently for this study from the refugee camps. Data was collected by using mixed type of questionnaire. Descriptive statistic was used for data analysis which has depicted through tables, pie chart and bar chart. Results: The finding of the study showed that 45.6% participants had multiple problems, followed by 16.8% participants who had other specific problems like musculoskeletal pain, visual problems and peptic ulcer. Urinary tract infection was the leading individual health problem with 11.4% of the sample group having it. 10.7% participants had hypertension, 6% had respiratory tract infection, 3.4% had nutrition deficiency, 4.75% had diabetes mellitus and 1.3% had sanitation & hygiene problems. Among the participants, 68.4% age ranged between 15-59 years. The study showed that, only 16.1% participants were satisfied with the quality of service they received while 37.6% participants said that they needed better services such as more laboratory test, radiological imaging, more medicine and more doctors. Conclusion: It is clear that refugees suffered from a variety of health problems, because their living condition and environmental situation were not similar like an independent nation. Further, basic amenities like medicines and other services were not available

Cardiovascular Disease and Diabetes: Two Sides of the Same Coin!

Cardiovascular disease (CVD) and type 2 diabetes (T2DM) are rapidly rising around the globe. Empirical researches demonstrated rapid increase in mortality and morbidity related to CVD and T2DM. Much of the diabetes-associated morbidity and mortality predominantly reflects its deleterious effect on macrovascular and microvascular diseases. The microvascular complications of T2DM include retinopathy, neuropathy and nephropathy and the macrovascular complications include ischemic heart disease, cerebrovascular disease and peripheral vascular diseases. Research indicates that coronary heart disease (CHD) is the major cause of mortality in people with T2DM. Herein, this chapter reviews relationship between CVD and T2DM, associated complications and effectiveness of relevant treatment modalities to treat/prevent diabetic macrovasculopthy. Macrovascular disease occur due to underlying obstructive atherosclerotic changes of major arteries which cause functional and structural abnormalities of blood vessels. The long-term complications can be controlled and prevented by controlling glycemia, maintaining normal lipid profiles, adopting a healthy lifestyle and using pharmacological interventions. Clinical trials have shown that lifestyle interventions help in prevention and reduction of CVD risk, but evidence for long-term CVD outcomes is lacking. A multidisciplinary approach involving patients, health professionals and researchers and governments should be undertaken to reduce the incidence and prevalence of diabetes-related cardiovascular complications

Patient Satisfaction in Chamber Setting in Bangladesh measured by Patient-Doctor Relationship Questionnaire (PDRQ-9 Bangla)

Background: Assessment of patient satisfaction is crucial but there is significant lagging in this sector. Patient satisfaction is an important indicator of health care quality as well as a predictor of treatment adherence. The Good patient-doctor relationship is considered as an integral part of the patient satisfaction. In Bangladesh, this domain is yet to be explored in a large scale. Aim: It was aimed to look into the patient satisfaction level in chamber setting in Bangladesh measured using the patient-doctor relationship questionnaire (PDRQ-9 Bangla). Methods: PDRQ-9 is a short yet excellent tool for assessing the patient-doctor relationship. The data collection was done in private chamber setting by the PDRQ-9 and analyzed. Results: Though the result was not completely in line with the existing literature, the PDRQ-9 was found to be a useful and brief measurement tool in the context of the patient-doctor relationship. Conclusion: Large-scale research in this particular aspect of patient satisfaction in future may provide a more succinct resul

Perceptions of medical students regarding community-based teaching experiences: an observation from Bangladesh

Introduction: Community orientation in medical education, which prepares medical students to become more effective practitioners, is now a global movement. Many medical schools around the world have adopted the concept as the main curricular framework in order to align learning programs with the needs of the community and the learner. Despite many changes over the past few decades, many improvements are still needed in medical education in Bangladesh. This study investigated medical students’ perceptions of the community-based learning experiences incorporated into the Bachelor of Medicine, Bachelor of Surgery (MBBS) degree at Uttara Adhunik Medical College, Dhaka (UAMC), Bangladesh. Methods: A total of 135 students from three undergraduate year levels of the MBBS degree at UAMC, Dhaka, Bangladesh, undertook study tours (community-based teaching, CBT) as a part of a community medicine course and visited a medical college, two rural health centres and a meteorology centre in the Cox’s Bazar district, 400 km from Dhaka city. A questionnaire was used to assess the perceptions of students regarding the administration, organisation and learning experiences of the study tours. Students were required to write reports, present their findings and answer questions in their examinations related to the study tours and CBT. Results: The majority of the students agreed or strongly agreed that the tour was a worthwhile (93%) and enjoyable (95%) learning experience that helped them to understand rural health issues (91%). More than half of the students reported that the study tours increased their awareness about common rural health problems (54%) and provided a wider exposure to medicine (61%). Only 41% of students reported that the study tour increased their interest in undertake training in a rural area. A substantial number of students also expressed their concerns about the planning, length, resources, finance and organisation of the study tours. Conclusions: Overall, the study tours had a positive effect, enhancing students’ awareness and understanding of common rural health problems. As study tours failed to increase the motivation of the students (approximately 60%) to work in rural areas, CBT in the medical curriculum should be reviewed and implemented using effective and evidence-based models to promote interest among medical students to work in rural and underserved or unserved areas

Depression and Associated Factors among International Students in a Private University of Bangladesh

Background: Depression is the second major cause of disability and is a principal source of disease burden worldwide which is quite common among international students. Aim: This study explored the depression and its associated factors among international students of a private university in Bangladesh. Methods: This cross-sectional study was conducted among 149 international students at a private university in Dhaka, Bangladesh using the Center for Epidemiologic Studies Depression (CES-D 10) Scale. Results: The prevalence of depressive symptoms among international students was 47.7%. Students’ age, marital status, satisfaction with living conditions and problems concerning studies, food, homesickness, finances, accommodation, and health were significantly associated with depression. Conclusion: This study concluded that there is an unmet need for psychological support for international students studying in Bangladesh. Appropriate support services should be directed to them to help and to overcome the challenges they face

Does household food insecurity influence nutritional practice of children age 6 to 23 months in Bangladesh?

To examine the prevalence of household food insecurity (HHFI) among children aged between 6-23 months in Bangladesh. This paper also aims to identify the individual, household and community levels determinants of HHFI and the association between nutritional behavior and HHFI. Bangladesh Demographic Health Survey (BDHS), 2011 was used for this research. A total of 2,344 children were selected for analysis. Statistical analysis and tests were guided by the nature of the variables. Finally, logistic regression analysis was used to find out the association between independent variables and outcome. The overall prevalence of HHFI was 36.3% (95% CI: 33.6-39.0) among the participants (children). The prevalence of HHFI was significantly higher among children who did not receive nutritional items. In contrast, HHFI was more prevalent among children who were breastfed (37.0%) as compared to non-breastfed. Binary logistic regression analysis showed that children of illiterate mothers (adjusted OR: 2.20, 95% CI: 1.17-4.10), illiterate fathers (adjusted OR: 2.27, 95% CI: 1.41-3.66) and socio-economically poor families (adjusted OR: 11.35, 95% CI: 7.20-17.91) were more at risk of experiencing HHFI, whereas, rural children (adjusted OR: 0.72, 95% CI: 0.57-0.93) were more protective. In the adjusted logistic regression model, children who did not receive juice (adjusted OR: 1.54, 95% CI: 1.09-2.16) had experienced HHFI. The prevalence of HHFI among children is still high in Bangladesh. Therefore, to achieve the Millennium Development Goals, the Government of Bangladesh should priorities HHFI as a major public health issue. Strong collaborations among various stakeholders are also crucial to improve the situation
